Answer

$9.4\%$ respondents answered 'Never' or 'Rarely'.

Work Step by Step

The number of respondents having answered 'Never' or 'Rarely' is the sum of both the number of respondents having answered 'Never' and having answered 'Rarely'. In detail, $$125+324=449.$$ Now to calculate the percentage, we divide the number just found by the total number of responses and multiply it by $100\%$. $$\frac{449}{4776}\times100\%\approx9.4\%$$ $9.4\%$ respondents answered 'Never' or 'Rarely'.
